Dogs have a keen sense of hearing and smell, and are good at guarding doors. They can be trained into working dogs such as military dogs and police dogs.

Humans mainly use it to protect their homes.

Chen Zhisui's "Zai Jing Tang Ji" records: "A dog is loyal and virtuous by nature. Once the owner has adopted it, no matter how poor the owner is, the hungry will never forget home or run away from home. The owner has no food.

It is available, but my beloved one wants to live in another place, so I send it away several times, but it is never allowed. It goes out during the day, eats wild food, and returns home, and the owner treks to make a living, and it always makes a noise.

Follow closely and make people cry. Compared with dogs, cats are not as good as dogs, but if there is delicious food and a good nest, cats will be happy and forget about their original owners. "His "The Ballad of Dogs and Cats":

"Don't raise cats to feed dogs. Cats and dogs have different interests. Cats can't catch mice when they are full. They come to gather with people when they are rich. Dogs still guard the house when they are hungry, but they cannot drive away poverty." From an emotional basis, the dog's loyalty to its owner has

Two sources: one is dependence and trust on the mother; the other is obedience to the group leader.

This means that a dog's loyalty to its owner is actually a replacement of the dog's loyalty to its mother or group leader.

From the perspective of pedigree, modern domestic dogs can be divided into two categories: jackal pedigree and wolf pedigree.

The loyalty of jackal dogs is mainly related to the first source of emotion, which is mainly due to attachment and trust to their mother; this kind of mother can be anyone who is friendly to it.

The loyalty of wolf-blood dogs is mainly related to the second source of emotion, which is mainly due to loyalty and obedience to the leader of the dog group; for dogs, there is only one such leader in their life.

In this way, loyalty has different meanings for these two dogs of different origins.

For a dog of jackal origin, the so-called loyalty to its owner refers to loyalty to all people who express kindness to it, while for a dog of wolf origin, the so-called loyalty to its owner refers to one owner or an individual.

Master's loyalty.

A jackal-blooded dog can be loyal to all those who are friendly to it, but this kind of "loyalty" should not be loyal to a specific owner.

Because wolf-blooded dogs are only loyal to one owner in their lives, it can be said that wolf-blooded dogs are far more loyal to their owners than jackal dogs.

The reason why there is such a difference in the loyalty of the two bloodline dogs lies in the genetic differences between the two dogs.
